Cosmology with Tully-Fisher HI Galaxy Surveys

Joël Mayor, Anthony Carr, Khaled Said +7

The SKA Observatory will enable measurements of the Tully-Fisher relation for statistical samples of HI selected galaxies out to unprecedented depths and redshifts thanks to its un…

Unlocking the Full Potential of SKAO Extra-galactic Science with High-multiplex Optical Spectroscopy

Kenneth J Duncan, Natasha Maddox, Daniel J. B Smith +9

Parallel to the transformation in radio continuum and H I observations from SKAO pathfinders and precursors over the past decade has been the development of a new generation of mul…

Kinematically cold and warm planetary nebulae samples, HII regions and supernovae remnants in the disc of the face-on spiral galaxy NGC 628 (M74) -- The Planetary Nebulae Spectrograph with the H arm

Magda Arnaboldi, Ortwin Gerhard, Surya Aniyan +14

We present the results for the galaxy NGC 628 observed with the Planetary Nebulae Spectrograph (PN.S) equipped with the H arm. With the third PN.S arm, the H arm, we measure…

MIGHTEE-HI: Mass Models and Dark Matter properties

Anastasia A. Ponomareva, P. E. Mancera Piña, A. A. Vărăşteanu +17

Measuring galaxy rotation curves is critical for inferring the properties of dark-matter haloes in the Lambda Cold Dark Matter (CDM) paradigm. We present HI rotation curves and…

MIGHTEE-HI: The radial acceleration relation with resolved stellar mass measurements

Andreea A. Vărăşteanu, Matt J. Jarvis, Anastasia A. Ponomareva +8

The radial acceleration relation (RAR) is a fundamental relation linking baryonic and dark matter in galaxies by relating the observed acceleration derived from dynamics to the one…

MIGHTEE-HI: The star-forming properties of HI selected galaxies

Madalina N. Tudorache, M. J. Jarvis, A. A. Ponomareva +9

The interplay between atomic gas, the star-formation history of a galaxy and its environment are intrinsically linked, and we need to decouple these dependencies to understand thei…

Resolving the Disc-Halo Degeneracy II: NGC 6946

S. Aniyan, A. A. Ponomareva, K. C. Freeman +5

The mass-to-light ratio (M/L) is a key parameter in decomposing galactic rotation curves into contributions from the baryonic components and the dark halo of a galaxy. One direct o…

Resolving the Disc-Halo Degeneracy I: A Look at NGC 628

S. Aniyan, K. C. Freeman, M. Arnaboldi +6

The decomposition of the rotation curve of galaxies into contribution from the disc and dark halo remains uncertain and depends on the adopted mass to light ratio (M/L) of the disc…
